> Check if a {{JobGraph}} can be scheduled with the available set of resources (slots).
If the minimum parallelism is fulfilled, then distribute the available set of slots across
all available slot sharing groups in order to decide on the actual runtime parallelism. In
the absence of minimum, target and maximum parallelism, assume minimum = target = maximum
= parallelism defined in the {{JobGraph}}.
> Ideally, we make the slot assignment strategy pluggable.
